Donald Trump isn't done attacking Carly Fiorina. Trump tweeted an article Monday critical of the former CEO of Hewlett-Packard's leadership, after swatting at her on national television earlier that day.

The tweet came as she is rising in the polls in the Republican presidential primary after two solid debate performances. “She’s got a good line of pitter-patter,” the business mogul said on “Today” Monday morning. “She says the same thing over and over and over...you look at her, and it’s robotic.” He also claimed she had “a record of tremendous failure” in the corporate world.

Fiorina climbed to second place in the Republican presidential field after last week's GOP presidential debate, a new national CNN/ORC poll shows. Trump remained in first place with 24 percent support, while Fiorina had 15 percent support -- up from 3 percent in early September. During CNN's debate Wednesday, Fiorina and Trump argued over who was the better business leader, among other issues.

“Despite those difficult times, we doubled the size of [Hewlett-Packard], we quadrupled its top-line growth rate, we quadrupled its cash flow, we tripled its rate of innovation,” Fiorina said during the debate. “I was a terrific CEO; the board was dysfunctional.”

The article Trump shared Monday was a Politico column from a Yale business professor. "I have studied her business record, challenged her leadership abilities and have come to agree with the assessment that she was one of the worst technology CEOs in history. I stand by that evaluation," wrote Jeffrey Sonnenfeld, senior associate dean of Leadership Studies and Lester Crown Professor of Practice Management at the Yale School of Management in New Haven, Connecticut. "In the five years that Fiorina was at Hewlett Packard, the company lost over half its value. It’s true that many tech companies had trouble during this period of the Internet bubble collapse -- some falling in value as much as 27 percent -- but HP, under Fiorina, fell 55 percent." He also called Fiorina misleading and irresponsible.

Roughly 44 percent of likely GOP voters view Trump as the candidate who could best handle the economy. Fiorina was next, with 11 percent support. The CNN/ORC poll was conducted over the weekend and surveyed 1,006 adult Americans.
